Abstract
A grinder for grinding materials to produce a ground substance. The grinder includes a cabinet, a grinder motor retained in the cabinet, and a grinder mechanism coupled to the motor to grind the materials. A hopper is positioned in communication with the grinder mechanism to deliver materials for grinding. The container retainer is attached to the grinder for retaining a container in close proximity for capturing ground material dispensed thereby. An activation switch assembly is included with the grinder to selectively control the grinder and activate the grinder when a container is placed in a desired location. A substance settling assembly is included with the grinder for removing a container retained by the grinder to settle the substance as it is dispensed from the grinder to the container. A chaff retainer is provided for maintaining chaff included with the ground substance in mixture with the ground substance. A clean-out member is operatively attached to the grinder and selectively engageable with the chaff retainer for removing chaff from the grinder. A magnetic collection device is positioned in the hopper for capturing magnetic pieces which may be deposited in the hopper. An active ventilation system is also included with the grinder for actively and controllably removing heat from the grinder cabinet.
